Which T-bar row grip configuration activates the middle trapezius, rhomboids, and rear delts more efficiently while removing lower back fatigue?
B

✓ Accepted Solution
A wide neutral or overhand grip pulled to the upper abdomen/chest maximizes shoulder horizontal abduction, driving heavy activation into the middle trapezius, rhomboids, and rear delts for back thickness without strainin...
Recent electromyography and muscle thickness studies show seated leg curl outperforms lying leg curl. Is this due to greater hamstring stretch at the hip joint?
D

✓ Accepted Solution
The seated leg curl places the hip in 90 degrees of flexion, which stretches the hamstrings at their origin on the ischial tuberosity. Hypertrophy research proves muscle growth is significantly greater when trained at lo...
Should elbows be tucked against the ribcage for latissimus dorsi bias, or flared out at 45-60 degrees with a wide bar for upper back and rear delt growth?
B

✓ Accepted Solution
Tucking elbows closely to your sides (0-15 degree flare) aligns the pull with latissimus dorsi muscle fiber orientation. Flaring elbows out at 45-60 degrees with a wide grip shifts the load directly to the mid-traps, rho...
If I bend my knees slightly more on a Romanian deadlift during hip hinge, does it allow deeper hip flexion for glute growth vs stiffer legs for hamstrings?
C

✓ Accepted Solution
A moderate knee bend (around 15-20 degrees) held fixed throughout the hinge allows deeper hip flexion and greater glute stretch. Keeping legs completely stiff shifts the leverage primarily onto the hamstrings and lower b...
Many lifters set bench incline at 45 degrees, but research suggests 15-30 degrees reduces anterior deltoid takeover. What is the optimal incline setting?
D

Sports Nutritionist
✓ Accepted Solution
Electromyography studies confirm that a 15 to 30 degree incline optimizes clavicular chest head activation while keeping anterior deltoid engagement low. At 45 degrees or higher, shoulder front delts take over up to 40% ...
Setting the cable pulley at wrist height and pulling behind the back vs in front of the body: which angle provides better stretch alignment for the lateral deltoid?
B

✓ Accepted Solution
Behind-the-back cable lateral raises maintain continuous tension on the side delt in the stretched position (at the bottom of the rep) because the cable pulls directly across your body's plane. Setup the pulley at wrist/...
Because of the upward diagonal path of a landmine press, does it target the clavicular (upper) chest head, and how can I adjust body angle for sternal lower chest focus?
C

✓ Accepted Solution
Standard standing landmine press presses upward at roughly 45 degrees, heavily recruiting the clavicular (upper) chest head and anterior deltoids. To target lower/middle chest, lean forward into the bar or perform kneeli...
Does a wide grip on the EZ bar target the short (inner) head of the biceps brachii, while a narrow grip targets the long (outer) head and brachialis?
D

✓ Accepted Solution
Yes! A wider grip externally rotates the humerus, putting the short (inner) head of the biceps into a mechanical advantage. A narrower grip internally rotates the arm, emphasizing the long (outer) head and brachialis for...
When setting up for a Smith machine sumo squat, should feet be directly under the bar or placed 4-6 inches forward to maximize glute recruitment while minimizing knee strain?
C

✓ Accepted Solution
For a glute-focused Smith machine sumo squat, placing your feet 4 to 6 inches forward of the bar path is ideal. Because the Smith machine locks you into a vertical track, stepping forward allows your torso to stay uprigh...
I have mild lumbar spine disc history and conventional deadlifts give me lower back tightness. Will switching to a high-handle trap bar deadlift reduce spinal shear while still training the posterior chain?
C
Coach_Dave_CSCS
CSCS Coach
Yes! Biomechanics research from Swinton et al. demonstrates that the trap bar aligns the load closer to the body's center of mass, which significantly reduces the hip moment arm and lowers lumbar shear forces. Use the hi...
